I have a website which has a session system. In the main page i have a logout button which calls a logout.php file. The file contains:

    <?PHP
        unset($_SESSION['user_id']);
        unset($_SESSION['user_name']);
        unset($_SESSION['user_admin']);
        unset($_SESSION['user_coins']);
        unset($_SESSION['user_email']);
        unset($_SESSION['user_createtime']);

        header("Location: index.php");
    ?>

The file runs like it should, it ends the session but it doesn't do the redirect. It just ends the session and stops there. What can be the problem?

    most likely outputting before header. – Funk Forty Niner Oct 16 '17 at 18:56
  • Turn on error reporting - always when developing and testing code, at the top of your script `error_reporting(E_ALL); ini_set('display_errors', 1);` Almost certainly you are facing some variant of [How to fix Headers already sent](https://stackoverflow.com/questions/8028957/how-to-fix-headers-already-sent-error-in-php) – Michael Berkowski Oct 16 '17 at 18:58
  • If for example your real code has whitespace before the opening ` – Michael Berkowski Oct 16 '17 at 18:59
